Similar to @aprilsimnel‘s invention. I want a machine which can record sounds directly from the brain. It’s like… I often get music in my head, but there’s no way I can pen it down and it frustrates me. Therefore, as an added plus, this machine must be able to transcribe it down into sheet music from the music playing in my brain. This includes full orchestral works.

Kinda like @aprilsimnel‘s and @SaturatedBrain except it records dreams so you can play it back like watching a movie. I had a great astral projection type dream once and would love to replay that one over and over.

My other device would be a cell phone hearing impaired people can actually hear on. Oh and one more for us hearing impaired, a bracelet/watch that vibrates so we can get up on time since we can’t hear an alarm clock. anyone who creates this one, I want first dibbs on it, buyer, co-owner, whatever :-)
